<h1>Dialogs<a class="headerlink" href="#dialogs" title="Permalink to this headline">¶</a></h1>
<p>Most applications consist of a ‘permanent’ main window - typically a frame - and ‘temporary’ dialogs.</p>
<p>See <code class="docutils literal"><span class="pre">wxglade/examples/dialog</span></code> for an example application how to create and use dialogs.
The example opens the dialog on pressing a button or selecting a menu entry.</p>
<table border="1" class="docutils">
<colgroup>
<col width="100%" />
</colgroup>
<tbody valign="top">
<tr class="row-odd"><td><a class="first last reference internal image-reference" href="_images/DialogExample.png"><img alt="screenshot from running examples/dialog/dialog.py with the dialog open" src="_images/DialogExample.png" style="width: 200px;" /></a>
</td>
</tr>
</tbody>
</table>
<p>When you add a new dialog <img alt="dialog" src="_images/dialog.png" />, you will be offered to add some default buttons like <span class="guilabel">OK</span> and <span class="guilabel">Cancel</span>:</p>
<table border="1" class="docutils">
<colgroup>
<col width="100%" />
</colgroup>
<tbody valign="top">
<tr class="row-odd"><td><a class="first last reference internal image-reference" href="_images/NewDialog.png"><img alt="screenshot for new dialog" src="_images/NewDialog.png" style="height: 200px;" /></a>
</td>
</tr>
</tbody>
</table>
<p>These will be placed in a <span class="guilabel">StdDialogButtonSizer</span> which will arrange the buttons such that the ordering matches
the OS style guide.</p>
<p>Also, the buttons will use <span class="guilabel">StockItems</span> and e.g. <code class="code docutils literal"><span class="pre">button.SetDefault</span></code>,
<code class="code docutils literal"><span class="pre">dialog.SetAffirmativeId</span></code> and <code class="code docutils literal"><span class="pre">dialog.SetEscapeId</span></code> will be called.</p>
<p>These are the generated lines of code that are specific for stock item buttons and using them in a dialog:</p>

<p>The dialog is created and used like this:</p>

        <span class="nb">print</span><span class="p">(</span><span class="s2">&quot;User has hit OK&quot;</span><span class="p">)</span>
</pre></div>
</div>
<p>Please note that the dialog in the example file does not have the size property defined.
Therefore the dialog will be created with the minimum size that fits the content.</p>
